Subject [jira] [Commented] (HIVE-17840) HiveMetaStore eats exception if transactionalListeners.notifyEvent fail
Date Fri, 20 Oct 2017 19:25:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17840?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16213096#comment-16213096
] 

Alexander Kolbasov commented on HIVE-17840:
-------------------------------------------

The exception is consumed in SentryStore.addNotificationEvent():

{code}
    try {
      this.openTransaction();
      this.lockForUpdate();
      ...
      commited = this.commitTransaction();
    } catch (Exception var11) {
      LOG.error("couldnot get lock for update", var11); // Here
    } finally {
      this.rollbackAndCleanup(commited, (Query)query);
    }

{code}

> For example, in add_partitions_core, if there's exception in MetaStoreListenerNotifier.notifyEvent(transactionalListeners,....),
transaction rollback but no exception thrown. Client will assume add partition is successful
and take a positive path.
